Answer
Tube feet
Reason — Echinoderms move with the help of tube feet. Tentacles are found in animals like Hydra, jellyfish, and cephalopods (octopus, squid). Echinoderms do not use tentacles for movement.Jointed legs are a characteristic of Arthropoda, Echinoderms do not have jointed appendages. Fins are locomotory structures in fish, Echinoderms are not fish and do not have fins.
